Water Pollution


Water Pollution

by Team The WisdomPost & Sophia

The biological or chemical change in the quality of water due to the presence of contaminants in water is called water pollution. Most of this contamination as on date is due to various human activities. In fact, humans are responsible for the mass deaths of whales and other aquatic organisms often swept ashore at different beaches in the world. There is an urgent need to look into the measures to control water pollution although a lot many efforts and schemes have already been announced by the Government in this regard. To make the students aware of this we have prepared short and long essays for students which shall inform them about water pollution and the means to minimize it.


Water pollution is a serious environmental issue. Water is said to be polluted if its physical, biological, and chemical properties are deteriorated via anthropogenic and natural activities. Water pollution has affected the lives of humans and animals in all aspects. Water pollution is very hazardous to the environment.

The water we drink daily looks clean; however, it is contaminated with microscopic pollutants. Many families have installed water purifiers at home to ensure that their family members get to drink healthy water. However, this will not help curb the water pollution problem on the global level. We should pledge not to pollute the water and preserve the natural reservoirs in order to curb water pollution. A number of campaigns such as ‘clean Ganga’ are run by the government and NGOs that have helped enlighten the population about the issue. More steps are required to be taken to ensure an adequate level of clean and pollution-free water for the survival of life on the planet.



The consumption of water forms a large part of our physical health. Aside from this obvious fact, water is an important aspect of our ecosystem. However, for water to perform its various functions, it has to be kept pure as contaminated water would lead to adverse environmental and health consequences.

Water pollution is the introduction of foreign material into our water bodies like lakes, streams, rivers or groundwater. This introduction, 9 times out of 10 is usually a result of human interference. Through various activities, sometimes inadvertently, we pollute our ecosystem with toxic materials dumped into our water.

Causes of Water Pollution:

One of the most popular features of water is also the cause of water pollution. Water is a “Universal Solvent” which simply means that it can dissolve almost any substance. Consequently, it is also why toxic substance mixes with water effortlessly. These toxic materials could be from traceable sources such as factories, farms, sewage etc. They are sometimes less traceable sources such as pollution in the air.

Water Pollution Effect on our Environment:

The first organisms that come in contact with polluted water are creatures living in the water. The effect of water pollution on aquatic animals depends on the kind of material introduced into the water. In extreme cases, it can lead to death of aqua species. It can also lead to a serious disrupting of the food chain. Finally, water pollution can lead to serious diseases in humans such as cholera and hepatitis.

Preventive Measures:

While the obvious way to reduce or eliminate water pollution is to stop industrial waste, doing just that and nothing more would not be enough. Preventive measures such as reduction in plastic consumption, controlling leaks in cars, using fewer pesticides or efficient disposal of chemicals would help us go the extra mile.

Clean environment is the basic life supporting system and pure water plays a prominent role in balancing the ecosystem. The environment provides us with the air we breathe, the water we drink, the food we eat and a shelter to protect ourselves. Access to fresh and clean water is a basic necessity of any living being for existence. But now it is least available. The adage, “Water, water everywhere, not a drop to drink,” rightly fits the current scenario.

No human activity can be possible without pure water. We face an acute shortage of clean drinking water and millions of people have been suffering from the shortage of pure drinking water. Despite knowing all these facts, people continue to contaminate water bodies recklessly exploiting the natural source of drinking water and risking the lives of millions of aquatic species.

Address the issues:

Water pollution poses a significant threat to the ecology and sustenance of life. The first and foremost cause of water pollution is the dumping of industrial wastes directly into the water bodies, and catchment areas without proper treatment. Aquatic species consume these harmful chemicals and become a huge menace to the ecosystem. It also leads to the reduction of oxygen content in the rivers and lakes.

Also, ruthless usage of fertilizers and pesticides in agriculture, are a reason to pollute water bodies. Uncontrolled discharge of wastes and improper sanitation also contribute to water pollution. When humans and animals intake water from these polluted rivers and lakes, it affects the health adversely. You can easily identify impure water from its color.

Moreover, such polluted water bodies become the breeding center of microbes and a reason to spread waterborne diseases and epidemics such as typhoid, diarrhea, cholera, etc. The underground water resources also get polluted when the contaminated water seeps through the soil.

The most critical step to prevent water pollution is to adopt appropriate waste management policies. Setting up of wastewater treatment plants can resolve this issue and hence we can protect our natural water resources from contamination and embrace an eco-friendly life.
